Handheld and mobile products including smart phones, mobile phones, radios, remotes and other gadgets are becoming increasingly complex yet are being subjected to more abuse than they have ever before. Drop testing is used to assess the fragility of these products by subjecting them to repeatable impacts similar to those they will experience with an end user.

Drop testing & repeatability

product-drop-testersEvery time a new device hits the market it’s quickly followed by multiple YouTube videos of first time users running informal drop tests, like here. The problem with leaving this type of testing to the customer is you have next to no control over repeatability. Product comparisons are next to useless unless you’re dropping from the same height, in the same orientation, on the same impact point.

Our testers are designed to drop test products up to 1kg in weight from a repeatable height in varying orientations, ensuring that the testing you conduct provides solid data to gauge product weakness.

We have two Heina drop testers available for use – having two allows us to benchmark products side by side, allowing you to quickly ascertain whether your new product is up to scratch.

What kinds of products?

phone-drop-test-orientationDrop testing is typically performed on small (<1kg) products that are either used in the hand, or in mobile situations. Any piece of equipment that can possibly be dropped should be drop tested during development to ensure you’re not up for surprises. A list of typical products we can test includes:

  • Cellphones, mobile phones, smartphones
  • Tablets
  • Two-way radios, mobile radios
  • GPS units, both handheld and vehicle mounted
  • Remote controls
  • Transmitters & receivers
  • Mobile EFTPOS units
  • Flash drives, hard drives and pen drives
  • Medical devices
  • Test equipment including handheld meters
  • Tools, analysis equipment and more.
  • Torches, head mounted illumination, etc.

Drop testing standards

Whilst there are many standards available for use most of the time the standard leaves it to you to determine the right drop height and provides a minimum quantity of drops to perform on each face, corner and edge. We’re able to help with recommendations for drop testing, so if you’re in need of help just contact us.

A list of common standards, though not entirely comprehensive, includes:

  • MIL-STD-810
  • IEC 60601-1
  • IPC/JEDEC 9703: Mechanical Shock Test Guidelines for Solder Joint Reliability
  • JEDEC 22B110A: Subassembly Mechanical Shock
  • JEDEC 22B104C: Mechanical Shock
  • JEDEC 22-B111: Board Level Drop Test Method of Components for Handheld Electronic Products
  • MIL-STD-202
  • IEC 60068-2
  •  IEC 60950
  • GR-63-CORE
